Need shrubs or plants which will use lots of water!
I've got a house built on a steep slope, and on the uphill side, despite french drain, grading, etc., we still end up with a slightly soggy area in the 6-foot or so space between the house and a terraced planting bed where the uphill slope begins.
I've always had to solve planting problems in areas which didn't get enough water, and now it's the opposite problem - I'd like to plant something in here which will suck up as much of the water in this soggy spot as possible.
As I said, it's a soggy spot which receives filtered morning sun and full early afternoon sun. It also needs to be something which will grow happily in this northern edge of zone 6, and won't have such a root system that it will interfere with the french drain. Any suggestions?
